Latest data on lecanemab and exidavnemab to be presented at the 2025 AD/PD™ congress
Stockholm, March 27, 2025 – BioArctic AB (publ) (Nasdaq Stockholm: BIOA B) today announced that the company and partner Eisai will present data on real-world use of lecanemab at the 2025 International Conference on Alzheimer’s and Parkinson’s Diseases and related neurological disorders (AD/PD™), to be held in Vienna, Austria, and virtually April 1-5. In total, lecanemab will be featured in six presentations and exidavnemab in one presentation.
Lecanemab is the result of a long-standing collaboration between BioArctic and Eisai. The anti-amyloid beta (Aβ) protofibril antibody was originally developed by BioArctic based on the work of Professor Lars Lannfelt and his discovery of the Arctic mutation in Alzheimer’s disease.
At AD/PD, Johanna Fälting, BioArctic’s Chief R&D Officer, will hold one oral presentation on exidavnemab, the company’s proprietary drug candidate aimed at treating synucleinopathies. BioArctic will also present one poster related to lecanemab in Alzheimer’s disease.
In addition to BioArctic’s presentations, Eisai will present four oral presentations and one poster presentation on lecanemab. These presentations will include the latest findings from real-world clinical evidence of lecanemab in the United States, efficacy and safety outcomes in apolipoprotein E ε4 (ApoEε4) heterozygous carriers and non-carriers in the Phase 3 Clarity AD clinical study, and a subgroup analysis of Clarity AD open label extension study in the Asian region.
Eisai will sponsor two symposiums on Alzheimer’s Disease.
Bridging the Gap in Alzheimer’s Disease: From Pathophysiology to Treatment Strategy featuring three leading global experts in the field of Alzheimer’s Disease, Dr. Dennis J. Selkoe (chair), Dr. Michael Heneka, and Dr. Miia Kivipelto. The symposium aims to enhance understanding by providing expert insights into the key drivers and mechanisms of Alzheimer’s Disease pathophysiology and neurodegeneration, the rationale for targeted approaches to anti-amyloid-β therapies, lessons from past drug development, and emerging treatment strategies.
Transforming Outcomes in Early AD: A Focus on Intervention and Management featuring prominent clinical experts in the field of Alzheimer’s Disease. The symposium will provide updates and insights into early Alzheimer’s Disease treatment from various perspectives, as well as information on future treatment directions.

About the collaboration between BioArctic and Eisai
Since 2005, BioArctic has a long-term collaboration with Eisai regarding the development and commercialization of drugs for the treatment of Alzheimer’s disease. The most important agreements are the Development and Commercialization Agreement for the lecanemab antibody, which was signed 2007, and the Development and Commercialization agreement for the antibody Leqembi back-up for Alzheimer’s disease, which was signed 2015. In 2014, Eisai and Biogen entered into a joint development and commercialization agreement for lecanemab. Eisai is responsible for the clinical development, application for market approval and commercialization of the products for Alzheimer’s disease. BioArctic has the right to commercialize lecanemab in the Nordic region under certain conditions and is currently preparing for commercialization in the Nordics together with Eisai. BioArctic has no development costs for lecanemab in Alzheimer’s disease and is entitled to payments in connection with regulatory approvals, and sales milestones as well as royalties on global sales.
